CAR-UNLOADING DEVICE.

Application filed December 13. 1920.

To all whom it may concern:

Be it known that I, FREDERICK W. Cowm, a subject of the King of Great Britain, and resident of the city of Montreal, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in CarUnloading Devices, of which the following is a full, clear, and exact description.

This invention relates to improvements in devices for unloading grain and the like from cars, and the object of the invention is to provide means for quickly and com pletely unloading the car without handshovelling.

A further object is to provide means for automatically removing the inner or grain doors of the cars. Various other objects and advantages will be apparent from the following description.

The device consists briefly of a tilting table adapted to hold a car rigidly in positionthereon, and a mechanically operated baffle plate with means for forcibly inserting the same in a car to remove a grain door and permit emergence of the grain.

In the drawings which illustrate the invention:-

Fig. 1 is a side elevation of the device showing a car in position thereon.

Fig. 2 is a plan view of the table and mechanism thereon, the position of the car being indicated in broken lines.

Fig. 3 is an end elevation of the device.

Fig. 4 is an enlarged elevation of the baffle operating mechanism.

Fig. 5 is an enlarged side elevation, partly in section, of the car placing and holding means.

Referring more particularly to the drawings, 11 designates a pair ofheavy plate girders connected together by transoms 12 and pivotally mounted at their centres on a pin 13 suitably supported in the upper part of a pit 14. At any suitable point, for example between the girders, a motor 15 is provided preferably driving a counter shaft Serial No. 430,296.

erably extend substantially parallel with and between the girders. Conveniently the shaft 17 may be located below the shaft 18 as shown, the shafts being, of course, supported for revolution in suitable bearings. The shaft 17 carries toward each end thereof a wormj21 meshing with a worm wheel 22 which drives, through a suitable gear train, the pinion 23. This pinion meshes with a grooved rack 24 rigidly mounted at the end of the pit 1 1 and circularly curved from a centre in the axis of the pin 13. It will thus be seen that there is a rack and pinion mechanism at each end of the pit and that by operating the motor one end or the other of the girder pair will be drawn down into the pit by the pinion travelling on the rack, so that the girder pair will be inclined as shown in broken lines, Figure 1. By operating the motor in the opposite direction the girder pair may be inclined in the opposite direction.

The shaft 18 is screw-threaded at its opposite ends, the threads being of opposite hand. The screw-threaded portions of the shaft operatively engage at each end with a carriage 25 and movable in the longitudinal direction of the girders on rails 26. Each carriage supports a very strong toggle lever 27, the outer end of the lever being connected to the outer end of the carriage and the inner end of the lever is connected to a transverse shaft 28 slidably supported toward the inner end of the carriage in slots 29. The ends of this shaft project beyond the carriage and engage at certain times between lugs 30 and 31 carried by brackets 32 supported from the rails 26 upon which the carriage travels. The upper lug or projection 30 projects downwardly into the plane of the slot and shaft, as clearly shown in Figure 5, while the upper ends of the lugs 31 are at about the level of the bottoms of the slots 29. The inner end of each slot is provided with a depression or notch 33 adapted to receive the shafts 28. A beam 3 1 is suspended from the shaft by plates 35 and is located below the tracks 26 to hold the carriage against jumping OK the tracks.

Stops or rests 36 are pivotally mounted at each end of the pit in position to swing under and support the ends of the girders. These rests are connected by any suitable means 37 with suitably disposed operating levers 38.

Track rails 39 are mounted upon the girders, one of these rails being at a higher level'than the other, so that a car standing thereon will be tilted laterally. As this lateral tilting of the car will throw the centre line of the under-frame out of the longitudinal centre line of the track the toggle levers and their carriages, which are designed to engage the couplers of a car, are located slightly nearer the lower rail, as clearly shown in Figures 2 and 3. Suitable platforms 40 for operators are carried at the remote sides of the girders.

The girder supporting the lower rail 39 carries at some distance from it and at a suitable point in its length, a column 41 supported by bracings 42 forming a very strong bracket. This column is approximately perpendicular to the inclined transverse plane of the track and will therefore be substantially parallel with the side of a car standing on said track. The column'carries a reversible motor 43 geared to a shaft 44 upon which are Vertically spaced right and left hand worms 45 meshing with worm wheels 46 having, driving connection with pinions 47. A pair of heavy rack-toothed bars 48 are support ed on the column by suitably disposed guide rolls 49 and are in mesh with the pinions 47, whereby said racks may be moved. These racks travel in planes parallel with the plane ot' the track but do not move exactly transversely of the track. The angular relation between these racks and the track is clearly shown in Figure 2, and is such that the racks will pass through the .doorway of a standard box car, standing on the track, close against the jamb and if extended across the car will strike the far car door at substantially its centre line. This is clearly illustrated in Figure 2. The ends of the racks adjacent the track are rigidly connected by a strong post 50, to which a suitably formed baffle plate 51 is hingedly connected in such a mannerthat the plate may lie close against the racks 48 when the same are extended as shown in dotand dash lines, Figure2. The lower edge of thisplate is designed to lie parallel with the floor of a car standing on the tracks and as car floors are nearly all r of the'same height only a small amount of.

adjustment will benecessary. This adjustmentisobta ined automatically by making the hinge lugs 52 of the baflle plate shallower thanthe recesses in the post in which they operate, so that the plate may have a certain rise and fall. -The leading edge 53 of the post is not'quite parallel. with the side of a carbut is nearer the car at the top than at the bottom, .as shown in Figure 3. This edge is provided with-teeth 54. i

A shield 55 iscarried by the platform 40 between the column 41 and the position oecupied by the sideof a car and is provided with wings 56 which will fill the spaces belocated in the pit and adapted to serve any suitable form of conveyor (not shown).

The operation of the device is as fol lows The girders, which form a tiltable table, are arranged horizontally and the rests 36 inserted under the ends thereof. The r toggle levers are flattened out and the racks 58 retracted to the position shown in Figure A. car of grain 'or other material to be unloaded is run onto the table and located approximately in the centre thereof. The motor 15 is started in the proper direction and the clutch 20 thrown in to operate the shaft 18 and draw the carriages 25 toward the centre of the table. The outer ends of the toggles being supported by the carriages are. drawn in whilethe inner ends of the toggles are held by the shafts 28 engaging the lugs 30. In this way thetoggles are raised from the flattened position shown in the dot and dash lines on the left hand end of Figure 1 through the intermediate position shown in Figure 5 to the fully elevated I position shown in Figure 1 which brings the buli'ers 27 of the toggle into alignment with the couplers of the car. l/Vhen the carriages have been moved to fully elevate the toggles the slots 29 thereof have been moved past the shafts 28 until the notches 33 are under the shafts and the'shafts drop into these notches. This dropping of the shafts releasesthem from engagement with the lugs 30 and brings them into position between the lugs 31 at opposite ends of the table. 7 Continued movement of the carriages will now draw the elevated toggles bodily toward the centre of the table until they engage the couplers of the car and shiftthe car until itis estactly centered on the table and one of its side doors opposite the shield 55. The clutch now thrown out. The cross'beams 34- suspended from the carriages under the tracks 26 keep the thrust of a car against the toggles from lifting the carriages oil the Y drawing the nails with which the door is usually secured. The difference between the inclination of the car side and the leading edge of the post results in the boards of which the door is usually formed being freed successively from the top downwards; Ob-

vionsly all the boards may be freed simultaneously or the bottom board freed first. Preferably, however, the topmost board is loosened first so that as soon as its end is freed the grain behind it may flow around the freed nd and escape, thus relieving the pressure. In this way the grain door is freed from one jamh of the car doorway with a comparatively small expenditure of power, the grain flowing out around the freed end of the door and reducing the pressure against the door. The grain which escapes flows out througlrthe car doorway and is directed by the shield 55 and its wings into the opening 57. As the post advances across the car floor in the angular direction previously described it swings the grain door around its point of attachment to the other door jamb and gradually withdraws the securing nails. The pressure of grain flowing out around the loosened end of the grain door presses against the shield 55 and swings it to about the angle shown in full lines Figure 2. [t will be understood, however, that the door is not at the angle shown in full lines F igure 2 when withdrawn from the car but assumes this position only by the pressure of grain against it. the time the post has advanced into contact with the far or closed door of. the car, the grain door at the loaded side has been completely separated from the car and has been carried forward by the engagement of the teeth 54 therein. As soon as the baffle plate has been carried completely across the car the motor 43 is stopped.

When the clutch 20 is thrown out the rests 36 are withdrawn from under the girders and the clutch 19 immediately thrown in so that the motor drives the shaft 17 to impart movement through the gear train 22 to the pinion 23 and cause the same to draw itself down on the curved rack at the right hand end of the device. so that the table and car thereon are tilted to the position shown in dot and dash lines, Figure 1. In this tilted position the car is held securely by the toggles 27. As the column 41 is fixed relatively to the table it is obvious that the relation of the column to the car is notaltered in any way. It will be noted by comparision of Figures 1 and 2 that the edge of the doorway against which the racks 48 operate is now elevated so that not only the grain immediately at the loosened end of the grain door but all the grain from the doorway to the elevated end of the car rushes toward the doorway and presses against the battle plate 51 which swings by gravity and by the pressure of the, grain against the lower door jamb. The inclination of the car is suflicient for all the grain therein to run out through the doorway, this movement being assisted by the lateral inclination of the car. While the tilting of the car and opening of the grain door have been described in sequence it will be understood that they occur simultaneously and are so timed that the battle 51 is carried completely across the car at, or shortly before, the maximum inclination is obtained. In this way one half of the car is unloaded. No grain will lie upon the sharply sloping car floor unless it be a small amount lying against the lower edge of the baflle plate. Any such small amount of grain may be withdrawn in a second or two by a hand-scraper without it being necessary for the operator to enter the car. With freely flowing material such as wheat, the elevated end of the car will be completely empty by the tim the battle has been moved across the car. I

The direction of the motor 15 is now reversed and the car swings to horizontal po- 'sitio'n, whereupon, the pinion at the right hand end disengages its rack and the pinion at the left hand end engages its rack and draws the left hand end of the car down until an inclination equal and opposite to the first is attained. As the car rights itself the pressure of grain in the lower or loaded end is directed upon the battle plate owing to the fact that the grain door has been wrenched free from the door jamb. This grain pressure causes the baffle plate to swing to a position close against racks 48 as shown in broken lines, Figure 2. As soon as the elevation of the loaded end commences the grain rushes toward the doorway and is directed out by the baffle plate as before. Vith free flowing material the entire contents of the second end of the car will have run out by the time the maximum inclination is attained. The out-rushing grain carries with it the grain door which may be rescued by an operator standing at the doorway or may be allowed to pass through the chute 58 and be separated from the grain in the hopper. Any small amount of grain which lies against the baffle may be scraped out as previously described.

As soon as the second end of the car is empty the motor 15 is reversed to return the car to horizontal position. While the car is being righted the motor 43 is started in a reverse direction to retract the post 50 and battle plate. This retraction will be complete at, or slightly before, the time the car reaches horizontal. When the table returns to horizontal position the rests 36 are inserted under it to relieve the tilting gear of unnecessary stresses. The clutch 19 is now thrown out and the clutch 20 thrown in and upon the motor being operated in the appropriate direction the shaft 18 will revolve and force the carriages 25 toward the ends Of the girders. In the first part of this seen that a car may be very quickly and easily unloaded without recourse to manual labor. As a matter of fact, the time required from the placing of a full car to its removal empty will be under five minutes. This celerity of action is due to the fact that all manual handling and placing of the car is entirely eliminated. The buffers which block the car in position on the table operate automatically to centre the car. The freeing of the grain door and the insertion of the unloading baffle occur simultaneously with V the first tilting of the car and the removal of the grain door simultaneously with the second tilting of the car. The removal of the baffle plate from the empty car occurs simultaneously with the righting of the car preparatory to removal. The control of the whole apparatus is extremely simple and as it is by way of controlling the direction and stopping and starting of the motors 15 and 43 it is obvious that this control may be located at any convenient point without complication of mechanism. The rests 36 are merely precautionary and it is clear that their use may be omitted during the shifting of cars but it is practically a necessity to insert. these rests if the greater weight of a locomotive is passed over the device. The structure is simple and rugged and will operate to unload from any side door car any granular substances, such as ore, coal, gravel, sand and the like as well as the grain which has heretofore been mentioned. With less freely flowing material, such as ore or coke, a much greater inclination of the car will be required than with free flowing materials such as hard coal or grain.
